@eric-hughes-tiledb Could you take a look? This does not seem to work on macOS. It just fails to build with GCC on my old testing system and fails to link on Sonoma.

[barracuda156]

On a side-note, this test, like a few others, needs to link against libatomic for some archs (ppc, arm, mips):

[eric-hughes-tiledb]

The missing symbols Catch::StringMaker, etc. are entirely in the Catch2 library. We use it in header-only mode, which does not have this issue. My best guess, with limited information, is that (1) you've got a system-installed catch which uses a linked library, and (2) the build is picking up the system version, and thus (3) there's a missing library.

As for the GCC failure, which version? Our code does not compile on older versions.

[barracuda156]

@eric-hughes-tiledb Thank you for responding!

Unfortunately, building against bundled Catch2 fails for me: #4095
So I had to use an external one (and your guess is correct).

As for the GCC failure, which version? Our code does not compile on older versions.

gcc 13.2.0, recent enough, hopefully.

Or is this rather a bug in Catch2 itself?

UPD. This one is a Catch2 bug indeed, but fixed as of 3.5.2.
